I bought one about three weeks ago. Got the plain black model even though the gun shop had the new tan models, and the newest version with safety. I figured the safety was one more thing to go wrong, & after a somewhat troubled launch, why buy a new feature (to the P365) that could cause reliability issues?
After several hundred rounds of WWB & Herter's FMJ, I fired 115, 124, & 147 gr Speer GDHP in mixed magazines with no issues. Even successfully tried some standard pressure Underwood Xtreme Defender all-copper "end mill" rounds, which the Rohrbaugh didn't care for.. (Also fired some of the Underwood +P Xtreme Defender rounds successfully.)
I called Sig to order some spare parts, but all they had so far were Recoil Spring Assemblies. Recommended change interval is 2,500 rounds. The Sig rep then told me that they had just released a 15 round mag, so I bought one of those, too. Shooting a 15-round mag of Xtreme Defenders is like throwing $20 bills in the trash. Yikes!
Post-range session field strip and cleaning revealed no issues & no visible wear - even to the black coating on the barrel or the rails. So far, so good. But nothing will carry like the Rohrbaugh!!
